楠竹是我国的主要用材竹种,它主要靠地下鞭限吸收营养、发笋、成竹。弄清其地下部分的生长发育规律是制定正确的经营管理措施的依据。本文主要在于探讨竹鞭生长发育、出笋、退笋、成竹的发生规律,寻求增加发笋、减少退笋、提高成竹率和竹林产量的途径,为楠竹林的经营管理提供依据。概况 1975年6月我们在楠竹产区桃源县竹园大队进行了这项研究。试验地是大年竹林。林龄百年以上,近年来每年修山,隔年垦复,经营管理和生长都较好。密度每亩216.5株,平均眉围35厘米,其中新竹57株,老竹159.5株。林地竹鞭,实测0.4亩共长1080米,竹
Bamboo is China’s main timber bamboo species, which mainly rely on the underground whip to absorb nutrients, shoots, into bamboo. To understand the underground part of the law of growth and development is to develop the correct basis for management measures. This article is mainly to explore the growth and development of bamboo whip, bamboo shoots, bamboo shoots back, bamboo into law, to find ways to increase the incidence of bamboo shoots, reducing the number of bamboo shoots, bamboo shoots and bamboo yield, provide the basis for the management of bamboo grove. Overview In June 1975, we conducted this study at Zhuyuan Brigade in Taoyuan County, Nanzhu. Test is a large year bamboo. Aged more than a century, in recent years Xiushan, reclamation every other year, management and growth are better. The density of 216.5 plants per acre, the average Mei Wai 35 cm, of which 57 were Hsinchu, 159.5 old bamboo. Bamboo whip, measured 0.4 mu total length of 1080 meters, bamboo
